Saudi Aramco briefly surpassed Apple as the world’s most valuable company in September 2020.
Saudi Aramco overtook Apple in market capitalization on September 9, 2020, after Apple’s shares fell and Aramco’s relative valuation moved higher. The change was temporary, illustrating how market-cap rankings can change even without a major corporate event.
Aramco’s valuation reflects its position in global oil production and energy markets. Apple’s valuation reflects expectations about consumer technology, services, cash generation, and future growth. Comparing the two shows that the market’s largest companies can come from very different industries.
Market capitalization is not a permanent title. It equals share price multiplied by shares outstanding, so daily price movements can reorder the ranking. Apple soon regained the top position, and technology companies later dominated many global market-cap lists.
